Magnetic fields in galactic environments probed by Fast Radio Bursts
Ilya S. Khrykin, Nicolas Tejos, J. Xavier Prochaska +7
FRBs constitute a unique probe of various astrophysical and cosmological environments via their characteristic dispersion and rotation (RM) measures that encode information about t…
Empirical estimation of host galaxy dispersion measure towards well localized fast radio bursts
Lucas Bernales--Cortes, Nicolas Tejos, J. Xavier Prochaska +4
Fast radio bursts (FRBs) are very energetic pulses of unknown physical origin. These can be used to study the intergalactic medium (IGM) thanks to their dispersion measure (DM). Th…
FRB Line-of-sight Ionization Measurement From Lightcone AAOmega Mapping Survey: the First Data Release
Yuxin Huang, Sunil Simha, Ilya Khrykin +12
This paper presents the first public data release (DR1) of the FRB Line-of-sight Ionization Measurement From Lightcone AAOmega Mapping (FLIMFLAM) Survey, a wide field spectroscopic…
FLIMFLAM DR1: The First Constraints on the Cosmic Baryon Distribution from 8 FRB sightlines
Ilya S. Khrykin, Metin Ata, Khee-Gan Lee +15
The dispersion measure of fast radio bursts (FRBs), arising from the interactions of the pulses with free electrons along the propagation path, constitutes a unique probe of the co…
The Cosmic Baryon Partition between the IGM and CGM in the SIMBA Simulations
Ilya S. Khrykin, Daniele Sorini, Khee-Gan Lee +1
We use the Simba suite of cosmological hydrodynamical simulations to investigate the importance of various stellar and AGN feedback mechanisms in partitioning the cosmic baryons be…
The FRB20190520B Sightline Intersects Foreground Galaxy Clusters
Khee-Gan Lee, Ilya S. Khrykin, Sunil Simha +7
The repeating fast radio burst FRB20190520B is an anomaly of the FRB population thanks to its high dispersion measure (DMpc/cc) despite its low redshift of $z_\mathrm{frb}…
Searching for the sources of excess extragalactic dispersion of FRBs
Sunil Simha, Khee-Gan Lee, J. Xavier Prochaska +11
The FLIMFLAM survey is collecting spectroscopic data of field galaxies near fast radio burst (FRB) sightlines to constrain key parameters describing the distribution of matter in t…
The first measurement of the quasar lifetime distribution
Ilya S. Khrykin, Joseph F. Hennawi, Gabor Worseck +1
Understanding the growth of the supermassive black holes powering luminous quasars, their co-evolution with host galaxies, and impact on the surrounding intergalactic medium depend…
Dating individual quasars with the HeII proximity effect
Gábor Worseck, Ilya S. Khrykin, Joseph F. Hennawi +2
Constraints on the time-scales of quasar activity are key to understanding the formation and growth of supermassive black holes (SMBHs), quasar triggering mechanisms, and possible…
Evidence for Short Myr Lifetimes from the He II Proximity Zones of Quasars
Ilya S. Khrykin, Joseph F. Hennawi, Gabor Worseck
The duration of quasar accretion episodes is a key quantity for distinguishing between models for the formation and growth of supermassive black holes, the evolution of quasars, an…
He II Proximity Effect and the Lifetime of Quasars
I. S. Khrykin, J. F. Hennawi, M. McQuinn +1
The lifetime of quasars is fundamental for understanding the growth of supermassive black holes, and is an important ingredient in models of the reionization of the intergalactic m…
